Continuation part ofepplieation To all whom 2'25 may concern:

Be it known that we, JOHN SCHUMAGHER and Josnrn E. SCHUMACHER, bothcitizens of the United States, residing at Los An-' geles, in the countyof Los Angeles and State of California, have invented new and useful in.Apparatus for Finishing Plaster-Board and the like, 'of which thefollowing is a specification.

This invention relates to improvements lIl apparatus for finishingplaster board and the like, prior to the drying of the board. is in parta division of our application filed Serial No. 98,572, which culminatedin Patent N 0. 1,259,049, and resides in the provision of means forsupporting plaster board so that it may be readily transported andsafely handled while moist and before the hardening thereof without thetearing or derangement thereof.

In the method of handling plaster board such as this invention isassociated with, the newly made board is stacked one unit upon the otherhorizontally in relatively large sheets, and as these sheets are moist,the plaster not having become set at th s time, it is impossible to pickup the indlvidual sheets or units when lying in stacked relationhorizontally without a. resultant tear- 1 th Inasmuch as it sheets or.units I v in 'vertical or. substantially upright relation upon a-framewhich is run into a kiln in order to drythe plaster board, it is theprimary ob ect of this invention to provide a supporting means for thestacked sheets, which means may be disposed so as to lie insubstantially upright position and to thus dispose the sheets incorresponding position so that they may be readily individually handledwhile held in substantially upright position without the possibility ofbreakage, tearing or other derangements.

ing or derangement thereof.

Another object of the invention is to provide means ofthe characterdescribed which is simple as to construction,inexpensive-and capableofbeing readily and easily operated.

The invention further consists in the particular arrangement,combination, association and inter-relation of all of the parts andelements of the invention, such as hereinafter described, illustrated inthe accompanying drawing, and finally pointed out in the appendedclaims.
